It is, but the notch itself is about 45mm deep, the plasterboard in front of it had cracked to so I am assuming there must have been a bit of movement?
Hi all, I have discovered a decentt sized notch in on of my joists, it is a 65mm, 175mm depth joist with about 3m span, I currently have the ceiling down and would like to strengthen it. Could anyone advise the best way to go about this? Thanks
